Can a USB to stereo RCA cable be used for the input of this headphone amp?
A shopper
on Feb 8, 2019
BEST ANSWER: No. The USB is a digital connection and the RCA is for analog connections. The cable is not converting the digital signal to analog. You need to have a DAC (Digital to Analog Converter) to do the conversion. Once the signal is converted to analog you can connect an RCA cable from the output of the DAC to the RCA input of this headphone amplifier.

Yes, as long as your cable has a DAC in between. I understand that you have a cable that you connect to your PC on the USB port and has RCA on the other side, that means that the cable does have a mini DAC in between. You simply have to plug on the RCA input ports any cable that has a line Audio signal. Just be sure that your cable does not have an already amplified signal or you won't get the desired performance with this and any other amp. If you by the other side, mean that you want to plug the RCA to your source device and the USB to this amp, then No, as this amp does not have an integrated ADC nor a DAC and it won't make sense, in that case you need a cable with twin RCA to RCA and you would connect it to the Line out of your source device and to the Input signal of this amp.

I use my iPad for streaming flac files from my hard drives via Plex, Mp3s via Spotify and YouTube, and HQ files via Amazon Music HD, and Qobuz. I use a, lightning to usb a, camera adapter and a good quality monoprice usb cable to connect to my DAC/Liquid Spark amplifier with very good results. You could save a few dollars and use a lightening to usb c converter and a cheap dongle usb c, dongle DAC. To 3.5mm to rca cable to the Liquid Spark. But, ...well..., penny wise pound foolish is what I learned as a child. Now, I say “buy once cry once! YMMV. Cheers!

Unless the USB - RCA has a built in DAC, no this won't work. When plugging in the cable Windows would recognize it as a separate audio device and allow you to output audio through it. You can test with the right adapters.

Pro tip: When connecting to an iPad or notebook's headphone-out jack to the amp,
- set your volume level on the iPad to no more than 80 to 90 % of full volume, and
- only adjust your listening volume using the amp's volume knob.
This preserves a little headroom on the output of the iPad, to avoid clipping and distortion, but gives you most of the dynamic range of your digital source. Good as a general rule to follow when connecting any amp to a portable devices headphone-output.

Sure. Like any electronics, you just have to match your input and outputs. It sounds like you have both identified so it’ll work just fine. The only other solution is to put an external DAC between the laptop and the amp. Small sound quality improvement if you do.

Yes, this amp will work with headphone level output from a mobile device. Will need to keep the volume on the source (ipad) reasonable to avoid clipping. Pro is cheaper than running a dedicated dac between source and amp, con is not quite as good result.

Some reviewers tout a "tube like" sound when reviewing this amp. Do the "pre-outs" benefit from this sound character as well? I will be using this primarily to control my powered studio monitors for now.

In my experience, yes. I have owned several tube amps - including a really great Onix Melody 3 - and when used as a preamp this does smooth out many of the harsh characteristics of digital audio, whether from my computer (Dell>Modi 3> liquid spark>Tube Depot Cube 7)>Lucid White Omnis) or from my iPads (iPad>Spark>Tube Cube 7 or Virtue Audio Integrated > Lucid Whites). As always, YMMV. I use the Spark 80% preamp and 20% Headphone amp. For headphones, I use either Audio Carbon Nighthawks or HiFiMan 400I

Personally, I wouldn't consider the sound of the Spark "tube like" at all. I don't know where this originated from. While the bass is okay, the mids are recessed and the highs have a little too much "sizzle". Its sound signature is very similar to the ole' "smiley face" EQ setting. If that's your sound preference then you'll love the Spark.
To answer your question, yes the sound from the front jack and preamp outputs will be the same.

William, thanks for the speedy reply. I'm using Presonus Eris 4.5s which do have a volume control but the speaker placement has put it out of convenient reach. I recently purchased a Topping D10 and am using my Schiit Fulla 2 as my volume control for now. I'd like to divorce myself from the Fulla 2 completely eventually so the Liquid Spark is in consideration. Should be good!
The sound signature will carry over to the pre outs. The tube sound is a warm signature, there are no openings amps on the output stage which gives it that warmth.

Gain switch: is the quieter mode low gain and the louder high gain?
A shopper
on Dec 20, 2019
BEST ANSWER: This headphone amplifier has +3dB or +6dB gain. You use the +6dB setting for low sensitivity headphones. Low sensitivity headphone don't sound as loud as high sensitivity headphones for the same volume setting. The +6 dB setting adds 3dB of additional gain to increase the sound level. This makes up for rhe quieter sound you get from low sensitivity headphones. I noticed no difference in the residual noise floor coming from the amplifier in either setting. It sounds great!

How do I connect my Samsung S9+ android phone to liquid spark?
A shopper
on Nov 12, 2022
Hi,
I believe your Samsung s9+ has a standard 3.5mm TRS headphone jack. If so, you need a cable with a 3.5mm TRS connector on one end and dual RCA connectors on the other end. You would then plug the RCA connectors into the LR inputs (marked "I") on the rear of the Liquid Spark headphone amp. Sometimes music stores or online retailers will refer to this as a "Y" or breakout cable.
I am NOT affiliated with HOSA cables or Amazon, but a cable like this one shown on Amazon is likely all you need. (Cables are available in various lengths.)
I hope this helps.
Regards,
Fred

Without seeing a schematic, it's difficult to say whether there are any coupling caps in series with the output or not.
Most manufacturers will usually coupling caps on the inputs though just in case there is some DC present on the outputs of the source.

RCA connected single ended cables are generally used at shorter distances. For longer distances XLR connected balanced cables are recommended because of greatly improved noise cancelling/shielding and increased signal voltage. High quality optical toslink digital cables are recommended up to around 40 feet without degradation and could by extended by using quality powered splitters as boosters to a DAC- HP amp. Or, use short optical cable to Bluetooth 5.0 Apt-X HD transmitter for HQ Bluetooth wireless transmission to a similar receiver/DAC-HP amp. Cheers!

I have the Monoprice Modern Retro earphones and they work just fine with the Liquid Spark. The sound is fantastic.

I believe they are. I did a quick review of the subject on line and they seem to meet the criteria. However I confess to not being an expert in that field. So you might want to do some research on your own. Nothing in the literature that came with my phones specifically designates the drivers as electrostatic.

how do you connect it to an old A/V Receiver without using the pre out and only using RCA Cables?

BEST ANSWER: You would need to use the preamp output, or a monitor output from the receiver.

I would connect it to the tape (record) out of your receiver. This is a constant level output, unaffected by main volume setting. This way you have independent control of headphone volume (via the Liquid Spark's volume control) and speaker volume (via the receiver's volume control).

WIll this adequately drive 600ohm headphones?

BEST ANSWER: Based on the specs, it technically should. I would imagine that it will not be ear shaking but very decent. I have this amp but using it on 250Ohm Open Back Beyerdynamic DT990Pro and it sounds really good. Granted that it’s almost half the Ohm you have.

I use it to drive 250 ohm Beyerdynamic 990 phones and it has plenty of volume to spare. It's a great little amp

What is the DAC on this with Windows 10 PC ?
A shopper
on Feb 24, 2021
BEST ANSWER: Computer audio requires a minimum of a DAC and an amp. The computer sends the digital signal as input to the DAC. The DAC converts the digital signal to an analog signal and sends the analog signal to the amp.
You can use the DAC in your PC or a separate DAC. The model of DAC on your PC motherboard may vary from one model of computer to the another.
Monoprice carries multiple DAC’s including "Monolith by Monoprice Liquid Spark DAC by Alex Cavalli “ which looks like a good companion product for this amp.

Owned this for almost 2 years and suddenly I'm hearing static when turning the volume dial, followed by the unit disconnecting (red light), before turning back on again (white light). Seems to work fine when left alone. Any idea what could cause this?

This sounds to me like an oxidized volume potentiometer which could happen to any device with a potentiometer. A good contact cleaner would probably take care of the problem if you take care to apply an appropriate amount ONLY to the inside of the scratchy pot and rotate the knob back and forth. I would try that first and good luck

Excellent headphone amp!
Amazing headphone amp. Brings out detail from all my DACs. I use with Sundara headphones. Sturdy construction and long power cable. This is now my desktop amp because its sound is addictive.

Fantastic Little Powerhouse Preamp Right Out Of The Box!
A little powerhouse preamp that sounds GREAT straight out of the box. Plenty of gain to drive any headphone. Solid low end, clean and dynamic. However...if you want to kick it up to a whole new level here is a simple mod. (Warning: you are voiding any warranty if you do this mod) If you are familiar with circuit board layout and have the correct tools and solder, it will take an hour of your time. Otherwise, take it to a technician which shouldn't cost more than $50 or so. You'll need two 1000 uF 50 volt electrolytic audio grade capacitors ($2.00 each) solder each across the + and - 18 volt test points on the little marked strip on the board. WOW, what a difference! Bass is tighter and more powerful, mid-range is smoother, top end is sweeter, and there is more depth and sense of space. I compared it, before and after the mod, to three very expensive preamps and the result is so stunning that it comes very, very close to preamps costing 20 times the price! WHAT A BARGAIN! Kudos to the great designer Alex Cavalli. Remember though, it's a beauty right out of the box even without the mod.

Sounds awesome...but
It really does sound great however there is one thing I can't seem to get working, the Preamp (P) output. RCA outputs on the rear of the device does not send to my analog board inputs. I've tested other outputs there and they work but I cannot, after using standard trouble-shooting techniques of different cords, different devices get this device's preamp out to function. I am assuming I got a new one. The headphone output is superb though.

Bought this to drive my Monolith AMT headphones, notoriously power hungry, when listening to a variety of audio devices. It sounds amazing, has just enough power to light up the AMTs.
